Massachusetts Unrestricted Construction Supervisor License Practice Test

Samples of shotcrete used in shotcrete shall be taken not less than once for every how many cubic yards of shotcrete?

1. 25

2. 50

3. 75

4. 100

The correct answer is: 50

In construction practices, shotcrete involves the application of concrete through a specialized process that allows for a high degree of control over the mixture and application. To ensure the quality and consistency of the shotcrete, regulations dictate specific protocols for testing. Taking samples of shotcrete not less than once for every 50 cubic yards is a standard requirement. This frequency ensures that there is adequate representation of the material being used on-site, allowing for timely detection of any issues with the consistency, strength, or other properties of the shotcrete mixture. Testing at this interval helps verify that the batch meets the specifications and standards necessary for structural integrity and performance. The other potential sampling frequencies, such as 25, 75, or 100 cubic yards, do not align with the established guidelines for shotcrete testing. These alternative intervals might not sufficiently monitor the quality of the shotcrete and could lead to lapses in quality assurance in larger applications. Hence, the choice of 50 cubic yards strikes a balance between thorough quality control and practical construction practices.
